What message did the Roosevelt corollary send to the rest of the world?

The Roosevelt Corollary, articulated in 1904, asserted that the United States had the right to intervene in Latin American countries to maintain stability and order. It effectively positioned the U.S. as a regional police power in the Western Hemisphere, signaling to Europe that the U.S. would take an active role in hemispheric affairs and discourage European intervention. This policy reinforced American influence in the region and marked a shift toward a more interventionist foreign policy. Overall, it conveyed a message of U.S. assertiveness and a commitment to protecting its interests in the Americas.
